Z'J'PECIPICATION forming part of Letters Patent No. 350,948, dated()ctObGr 19, 1886. Application filed June 15, 1886. Serial N0.Q05,l9(i.No model.)

To all whom, it may concern:

Be it known that I, THnonon 0. L. SCHRADER, a resident of New York city,in the county and State of New York, have invented an Improvement inPencils, of which the following is a full, clear, and exact description,reference being made to the accompanying drawings, in which- Figure 1 isa central longitudinal section of myimproved pencil. Fig. 2 is a centrallongitudinal section of a modification of the same. Fig. 3 is a centrallongitudinal section of another modification of the same. Fig. 4 is acentral longitudinal section of what is shown in Fig. 3 in a differentposition.

This invention relates to a new construction of pencil for holding aloose lead; and it consists in the new combination of parts hereinafterstated.

In the drawings, the letter A represents the case or outer sheath of thepencil-holder, the same being bored longitudinally to receive within itsbore the lead B. At the end the sheath A carries rigidly attachedthereto a slotted projecting tube, a, of small diameter, but largeenough to embrace the lead B, said tube a terminating in biting-jaws I),which, when compressed, are adapted to hold the lead B, as in Fig. 1,but which, when loosened or opened, as in Fig. 2, will allow the lead toslide freely.

G is a sliding contracting tubethat is, a tube which is constructed topress the jaws I) against the lead whenever said tube isin one position,(see Figs. 1 and 3,) and to allow the said jaws to open when it (saidtube 0) is in the other position. (See Figs. 2 and 4.) The tube Cis heldin one position-the normal or contracting position-by a spring, (I,which is confined in place within a tubular extension, 6, of the case orsheath A. The said extension is of the same external diameter as thesheath A, and adapted to receive within it the smaller tube, G, and thespring d. The spring d is between the outer circumference of the tube 0and the inner circumference of the extension 6.

\Vhen the tube 0 is ot'the construction shown in Fig. 1that is, adaptedto press the jaws against the lead in its converging or taperingmouth-the spring (I, bearing against a flange, f, at the upper end ofthe tube 0, will normally hold said tube in the elevated positionagainst the end of the sheath A; but when the tube 0 is of theconstruction shown in Figs. 3 and 4 to wit, adapted to hold the jawsagainst the lead by contact with its diverging or flaring mouth-thespring d, pressing against a sh oulder,f*, of the tube 0, beneath it andagainst the end of the sheath A, will normally hold said tube inthelowered position, as shown in Fig.

1n the position shown in Figs. 1 and 3 the lead is firmly held bythejaws b. In order to move the lead, the tube 0 must be pulled forwardas in Fi 2 or ushed 11 )Ward as in 7 b 7 7 Fig. 4, so as to open thejawsand release the lead.

' Fig. 2 shows two leads held in the same sheath, the same sheath beingprovided with the means specified for holding and releasing each of saidleads.

By arranging the tube 0 to slide within the extension 0 of the sheath Athe lower end of the sheath proper is utilized as an abutment, (seeFigs. 1 and 4,) and the parts are confined within aperipherysubstantially equal to that of the sheath A.

I claim The combination, in a pencil, of the sheath A, having projectingjaws b, with the sliding tube (l, of less diameter than sheath A, fixedtube 6, of substantially the same diameter as the sheath A, and spring(I, the said spring being confined by the tube 6 and surrounding thetube 0, the end of the sheath A serving as an abutment, as specified.
